DENVER (CBS4)– Pot won’t fly at Denver International Airport but marijuana advocates say it’s their right to travel with it if they bought it legally.

There have been signs posted at DIA stating that pot is not allowed in the airport since the drug became legal Jan. 1. But there have been a few instances of people trying to take marijuana with them on airplanes.

Cannabis supporters claim it’s their right and airport officials say their hands are tied. DIA heard public comment on Wednesday during a hearing on a possible policy change regarding marijuana.
